Copy the ASN.1 modules from TS 101 671 V3.15.1 (2018-06) (historical)
still used by TS 102 232-1 and imports of the latter, adapted to
the naming convention here:

HI1NotificationOperations,ver7.txt as HI1NotificationOperations.asn
HI2Operations,ver18.txt            as HI2Operations.asn

Reformat the .asn files:
- 4 space indenting, including ensuring fields line up
- no tabs
- no trailing whitespace

No difference to previous when  git diff -b / --ignore-space-change
except for removal of some trailing blank lines.

Update IPAccessPDU.asn as per LI(20)P55006r1
